LIQUID-FUEL BURNER.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed October 24, 1914. Serial No. 868,491.

To all whom it may concern:

Be it known that I, HENRY G. Lrneznrr, a citizen of the United States, residing at Sheboygan Falls, in the county of Sheboygan and State of "Wisconsin, have invented certain new and useful Improvements in Liquid-Fuel Burners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in liquid fuel burners and has relation more particularly to a burner of this general character comprising a generating coil;

and an object of the invention is to provide a novel and improved device of this general character whereby a maximum of heat may be obtained with a minimum of fuel.

Furthermore, it is an object of the invention to provide a device of this general character having novel and improved means whereby the burner, or more particularly the coil thereof, is provided with a protecting casing to confine the initial generating fiame whereby the possibility of any adjacent parts becoming ignited is avoided.

The invention also has for an object to provide a novel and improved device of this general character wherein the protecting casing serves asa means for supporting the burner in operative position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved liquid fuel burner whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the ac companying drawings, wherein Figure 1 is a view, partly in elevation and partly in section, of a burner constructed in accordance with an embodiment of my in-,

vention; Fig. 2 is a fragmentary elevational view, illustrating a slightly modified form of construction; and Fig. 3 is a top plan view of the arrangement illustrated in Fig.2.

As disclosed in the accompanying drawings, 1 denotes a tubing adapted to be con nected with a suitable source of liquid fuel supply, such as kerosene, and under suitable pressure. The tubing 1 is bent to afford a substantially cone-shape coil C, with the lowermost convolution 2 in direct communication with the source of supply. The portion of the coil 1 at the apex of the coil is bent to afford a loop 3 disposed substantially longitudinally of the axis of the coil with the inner end portion of such tube disposed axially of the coil and having its lower extremity bent upwardly, as at 4, with the end thereof closed. The axially disposed portion 5 of the burner is provided therealong at predetermined intervals with the minute openings 6 through which the fuel is adapted initially to escape so that upon ignition, sufficient heat will be generated as to vaporize the fuel within the coil G whereby the burner will operate in a manner which is believed to be self-evident. It often occurs that the initial flame afforded by the fuel when in a liquid assumes such proportions as to possibly ignite elements in close proximity to the burner. In order to avoid this disadvantage, I position the coil C within a truncated cone 7 having its upper and lower faces open and longitudinally split, as indicated at 8.

While I do not desire to limit myself to any particular use of my improved burner, it is intended primarily to be employed in connection with vats and paraffin containers generally employed in the production of cheese, and by forming the casing 7 as has just been described, it may be readily and conveniently inserted within the fines of such vats or containers of varying diameters.

Disposed transversely of the casing 7 adjacent the smaller end thereof is a pin or bar 9 also disposed through the loop 3 whereby it will be perceived that the coil C is properly maintained within the casing.

While the burner, as hereinbefore set forth, has been found in practice to operate with a maximum of efficiency,I have also found in practice that the embodiment of my invention as disclosed in Fig. 3 may be employed with material advantage. The form of invention as illustrated in this figure is substantially identical to what has been previously described, except that the axially disposed portion 5 is imperforate and has its lower extremity terminating in the fiat coil 10 provided with suitable minute perforations 11, for a purpose which is believed to be clearly apparent to those skilled in the art to which my present invention appertains. 7

I also find it of advantage to secure to the inner surface of the cone 7, the strips 12 which interlock with the convolutions of the coil C whereby said convolutions are maintained in predetermined spaced relation. It is also to be observed that these strips 12 also serve as an additional medium for maintaining the coil C within the cone.

From the foregoing description, it is thought to be obvious that a liquid fuel burner constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. A burner of the character described comprising a coil, one extremity of such coil being disposed axially thereof and provided with openings, said axially disposed portion being bent upon itself atvits upper end to afford a supporting loop disposed above the upper end of the burner.

2. A burner of the character described comprising a coil, one extremity of such coil being disposed axially thereof and provided with openings, said axially disposed portion being bent upon itself at its upper end to afford a supporting loop disposed above the upper end of the burner, a casing substantially inclosing the coil, and means carried by the casing coacting with the loop for maintaining the coil within the casing.

8. A burner of the character described comprising a coil, one extremity of said coil being disposed axially thereof and provided with openings, a longitudinally split casing substantially inclosing the coil, and strips carried by the casing interlocking with the convolutions of the coil for maintaining the convolutions in predetermined spaced relation and serving as a medium for maintaining the coil within the casing.

A burner of the character described comprising a coil, the upper extremity of said coil being disposed axially thereof and provided with openings, said axially disposed portion being bent upon itself at its upper end to afford a supporting loop disposed above the upper end of the burner, and means disposed through the loop for maintaining the coil in an applied position.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
